ADJUSTA LE BRACKET.

Specification of Letters Patent.

Patented Au 21, 1917.

Application filed September 19, 1916. Serial No. 120,925.

To all whom it may concern:

Be it known that I, WILLIAM H. WAT- noos, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Adjustable Brackets, of which the following is a specification.

The object of the invention is to provide an adjustable bracket particularly adapted for attachment to various uprights such as poles, trees, door-frames, and window-frames, for supporting cameras, mirrors, and other objects, and which shall-be so constructed that the bracket may be carried in ones pocket or grip, or in a camera case without the slightest inconvenience; the construction and ar rangement being such that the bracket may not only'be readily attachedto, and detached from the support, but also that it is capable of such adjustments that it may be readily connected to supports of various shapes and dimensions.

The invention consists in certain novel details of constructions, combinations, and arrangements of parts as will be hereinafter fully described andthen claimed.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a perspective view of my invention shown as connected to a post or tree. Fig. 2 is a plan view of the same, the rubber sleeves carried by the supporting arms being shown in section. Fig. 3 is a side elevation of the same, and Fig. 4 is a detail of construction. Figs. 5 and 6 are detail views illustrating a slight modified detail of construction.

1 designates the supporting arms of the bracket having, what may be termed their outer ends, bent inwardly and pointed as at 2, and their opposite ends also bent inwardly as at 3, and pivotally connectedto a link 4, the said link having kerfs in which are fitted the reduced ends or tongues 5 of the inwardly extending ends 3 of the arms. The link 4 is formed with a slotted extension or lug 6 in which is pivoted at one end, a supporting arm 7 having its outer or free end pointed as at 8 so as to grip into the support to which the bracket is attached and to thus hold the arms 1 in their desired position. 9 desi nates a coil spring connecting the arms 1. lhis spring, serves the purpose of drawing the arms together and to hold the pointed ends 2 firmly into engagement with the support, and hence prevent accidental slipping of the arms when an object of reasonable weight is positioned thereon, The spring is designed especially for holding the ends 2 of the arms into engagement with the support, as, for instance, when connected to a metal post, it being understood that the spring is of suflicient tensile strength to afford enough friction to hold the bracket in place. V I

Slidably retained upon the supporting arm 7 isa post 10, having an obliquely arranged elongated slot 11 adjacent to one end through which the supporting arm-'7 passes. "The lower end ofthe' post is providedwith a threaded opening 12 to receive the shank of a thumb screw 13, whereby the post may be firmly clamped at any point upon the-arm 7 to which it is adjusted. The upper end of the post is formed with a threaded extension 1 1 to fit into the threaded opening in the body of, a camera (not shown), whereby the camera may be firmly held in position upon the bracket.

In practice the arms 1 will each be covered with a rubber sleeve 15 to prevent accidental slipping of the camera when the post is not used, and also to prevent the slipping of a mirror when the bracket is employed for supporting a shaving mirror when the device is connected to a window or a door frame. I also purpose providing the supporting arm 7 with a pin 16 to prevent the post from becoming detached from the said arm 7.

As shown in Figs. 1 and 2 of the drawings, the arms 1 are spread apart against the tension of thespring 9 so that the points 2 of the ends of the arms 1 may engage the object to which the bracket is to be connected. The supporting arm is then brought up into engagement with the support and adjusted thereto until the arms 1 are adjusted either to a horizontal position or an angular position with respect to the support as will be readily understood. The bracket is then ready to receive the object it is intended to support.

When the bracket is folded, the post 10 1 While I have shown and described my invention as adapted to be connected to a post or the frame of 'a'door or window, it'will be" points 2 of the arms.

While I have shown the supporting arm 7 provided with an adjustable post having a threaded section to receive the threaded socket in the base of the camera, I do'not wish to be limited to this particular arrangement, since it is obvious that the'link 4 may be formed with avertical, perforated ear or lug 6' adapted for cooperation bya member 17 having a threaded stud 18 extending therefrom, the said member being held and firmly clamped to the ear or h1g6 by a set screw 19 as shown in Figs. 5 and 6. ,By this arrangement, it will be obvious that the member 17 may be readily adjusted and clamped into vertical position or at an angle with respect'to the supporting arms 1 irrespective of the angle of the supporting arm 7, hence facilitating the adjustment of .a camera upon the bracket. It will be understood that by this arrangement, when a ca m: era is screwed upon the stud, the arm may be adjusted to "raise or lower, thev supporting arms 1 in order to adjustthe lensof a camerainto properalinement'with the object or view to be taken.

I claim is 1. An adjustablebracket, comprising sup porting armshaving their outer ends bent diipi's'of this patent nay be' "bbtahieil for inwardly and pointed, and their opposite ends bent inwardly and formed with tongues, a link having 'kerfs to receive said tongues and pivotally connected thereto, a

supporting arm carried by and pivotally connected to said link, a spring connecting said supporting arms, a post carried by said supporting arm having a threaded extension at one end for the purpose specified, and a clamping thumb screw fitted in its opposite end. I '2, An adjustable bracket, comprising supportingarms having their outer e'nds bent inwardly and pointed, and .their opposite ends bent inwardly and formed with reduced sections or tongues, rubber sleeves carri e d by said supporting arms, a link having ker fs to receive said reduced sections or tongues and pivot'ally connected thereto, and having a depending. slotted lug, a supporting arm pivoted at one end in the slot of said lug and having its opposite end pointed, a spring connecting said supporting arms, a post carried by said supporting arm having a threaded extension at one end for the pur pose specified, and a clamping thumb screw fittedin its opposite end; j v a In testimony whereof I have hereunto set my hand this 29th day of August, A. D. 1916. I I WILLIAM H. WATROUS'.
